是什么原因导致err'类型为lucene.codecs.Codec名称' Lucene42'的SPI类. [英] What causes err ' A SPI class of type lucene.codecs.Codec name 'Lucene42'

问题描述

无法弄清是什么原因导致的.名称为"Lucene42"的org.apache.lucene.codecs.Codec类型的SPI类不存在.您需要将支持此SPI的相应JAR文件添加到类路径中

Can't figure out what is causing ' A SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene42' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath'

推荐答案

请在以下文件中添加

文件夹: META-INF/services/

文件: org.apache.lucene.codecs.Codec

文本: org.apache.lucene.codecs.lucene54.Lucene54Codec

请在 https://anwaarlabs.wordpress.com/2017/02/25/lucene-an-spi-class-of-type-org-apache-lucene-codecs-codec-with-name-does-不存在/

此解决方案是为Lucene5.4定义的，也适用于Lucene 4.2.谢谢

This solution is defined for Lucene5.4 it also works for Lucene 4.2. Thanks
